Energy Generation

ABSTRACT

Various embodiments are described that relate to energy generation. A housing can retain a spring coupled to a gear set. As the spring experiences linear compression and extension, the spring can cause rotational movement in the gear set. The rotational movement from the gear set can cause rotation of a rotational magnet. The rotational magnet, when rotated about a coil set, can convert an energy. The energy can be used to charge a battery.

BACKGROUND

Electronic devices have a wide variety of uses and applications in modern society. These electronic devices use electrical energy to function. In one example, this energy is derived from a battery. As the devices are used, the battery level lowers and ultimately reaches a level so low that the electronic device does not function without a new battery, which can be expensive, or the battery being recharged. Therefore, it can be valuable to recharge a battery.

In one embodiment, a system can comprise a linear hardware component that can be configured to experience a linear movement sequence. The system also can comprise a conversion hardware component that can be configured to convert the linear movement sequence into a rotational movement sequence. The system additionally can comprise an energy generation hardware component that can be configured to generate an energy from the rotational movement sequence.

DETAILED DESCRIPTION

In one embodiment, energy conversion can occur from a housing. A person, as well as an item carried by the person, can experience movement. That movement can be captured and converted into electrical energy. As an example of this capturing, linear movement of a spring coupled to a backpack can be transferred into rotational movement. The rotational movement can cause a rotational magnet(s) to rotate. Rotation of the rotational magnet in conjunction with a coil assembly can be used to convert a kinetic energy (captured as a mechanical energy) into electrical energy.

FIGS. 1A-1D (collectively referred to as ‘FIG. 1’) illustrate various views of an embodiment of a housing 100 (described by the different views 100A-100G). FIG. 1A illustrates a first perspective view 100A of the housing 100. The housing 100 can retain a rack 110 coupled to a spring 120. The rack 110 can also be coupled to a user or an item of a user, such as a backpack (e.g., rucksack strap), purse, briefcase, computer satchel, etc. In one example, the rucksack (e.g., Modular Lightweight Load-carrying Equipment (MOLLE) rucksack) can have a rigid frame that aligns with a wearer's waist. The housing 100 can be coupled (e.g., affixed) to the rigid frame. The rack 110 can be coupled to a strap or other item of the rucksack, such as a strap from a shoulder area of the rucksack. The strap can weave through an end of the rack 110, by way of a slit 130, so that it is taught. As the rucksack is worn, the shoulder area and therefore the strap can experience linear movement (e.g., when decoupled from the hip-belt) due to movement of the rucksack upon the user. As the strap experiences linear movement, the rack 110 and spring 120 can experience the linear movement. In this, the spring 120 can be an example of a linear hardware component configured to experience a linear movement sequence.

In one embodiment, the spring 120 is a compression coil spring and therefore an example of an elastic energy storage hardware component in compression configured to be coupled to a connector (e.g., the strap). The compression spring can be in a neutral compressed position. As the rucksack moves up in response to user movement, the strap (e.g., coupled in tension) can pull the compression spring into decompression. Once the rucksack movement is complete, the compression spring can return to the neutral uncompressed position. This decompression and return to state position can be the linear movement sequence.

The linear movement sequence (e.g., completely linear or substantially linear) of the spring 120 can be converted into a rotational movement sequence by a conversion hardware component. In one example of the conversion hardware component, the rack 110 can rotate a gear set 140. As the spring 120 moves linearly, the rack 110 can move the gear set 140 rotationally (e.g., alternating clockwise and counter-clockwise).

The gear set 140 can be coupled to a rotational magnet assembly 150 that can function as an example energy generation hardware component configured to convert an energy from the rotational movement sequence. In one example, the rotational magnet assembly 150 can comprise twelve cube magnets that rotate around a stationary set of nine coils to convert 3-phase alternating current power. The gear set 140 and rotational magnet assembly 150 can be calibrated with one another. In one example, a gear of the gear set 140 that couples with the rack 110 can be at a ratio of 12.96 in comparison to the rotational magnet assembly 150.

The energy generated from the rotational magnet assembly 150 can, in one embodiment, be transferred to an electronic device. This transfer can be achieved by way of a port 160. The port can be configured to couple the housing 100 with the electronic device (e.g., smartphone, radio, etc.). A plug can be inserted into the port 160 to facilitate the transfer.

In one embodiment, the energy can be transferred to a battery. The port 160 can function as a battery retention hardware component configured to retain the battery. The port 160 can function to charge the battery with the energy. However, other configurations can be used. In one example, the battery can be removable, but physically integrated into the housing 100. In another example, the housing 100 can contain an incorporated battery that is recharged. The port 160 can connect the housing 100 to the electronic device and the incorporated battery can directly power the electronic device and/or be used to power an incorporated battery of the electronic device.

As illustrated, there are a gear set 140 and a rotational magnet assembly 150 on the sides of the rack 110. However, various other embodiments can be practiced other than what is illustrated. In one example, the rack 110 can directly couple to the rotational magnet assembly 150 without the gear set 140. In this example, the rack 110 can itself be the conversion hardware component configured to convert the linear movement sequence into the rotational movement sequence. In one embodiment, as opposed to connecting with a strap, the housing 100 can be self-functioning. The spring 120 can be a tension coil spring where the spring 120 is fixed at one end of the housing 100 and has a mass on the opposite end (e.g., the slit end). As the housing 100 moves (e.g., is jostled while within a woman's purse), the mass can extend the tension coil spring.

Conversely, if the spring 120 is a compression spring, then the mass can compress the compression spring. In one example, the housing 100 can be non-affixed to the purse and the stiffness of the compression coil spring can be relatively small. Therefore, the mass can move relatively freely to create the linear movement as compression and decompression. In one example, the mass and spring 120 can be designed such that the mass compresses the spring 120 in rest, but with relatively little movement, the mass can cause decompression. With other directional movement or a return to rest for the housing 100, the spring 120 can return to the compressed state.

FIG. 1B illustrates an exploded view 100B of the housing 100. The rack 110 and/or the spring 120 can be a capture hardware component configured to experience a movement sequence as a result of the spring 120 being placed in compression (e.g., by way of the strap, in tension, of the rucksack coupling with the rack 110 through the slit 130). The rotational magnet assembly 150 (e.g., along with the gear set 140) can be an energy generation hardware component configured to convert an energy from the movement sequence. The port 160 can be configured to operatively couple the housing 100 to an electronic device that is powered by the rotational magnet assembly and/or the housing 100 can charge the battery as discussed above.

In one embodiment, the housing 100 can function without the slit 130 and instead comprise a mass at the rectangular end of the rack 110. The rack 110 and spring 120 can be a capture hardware component, coupled to the mass, configured to experience a movement sequence due to movement of the mass resultant from movement of the housing 100. The rotational magnet assembly 150 (e.g., directly coupled with the rack 110) can function as an energy generation hardware component configured to convert an energy from the movement sequence. The port 160 can function along with an integrated battery of the housing 100 to power an electronic device with the energy. In one example, the energy generation hardware component can be configured to charge the integrated battery with the energy generated from the movement sequence. The integrated battery can be configured to provide power to the electronic device by way of the port 160.

The housing 100 can be low mass, low profile, and function as an energy harvester (e.g., charge the integrated battery). In one example, the housing 100 can be fastened to a frame of the rucksack (e.g., a waist portion of the frame). A shoulder strap of the rucksack can loop through the housing 100, such as through the slit 130 and looped with an end of the rack 110 (e.g., the strap is looped through the rack 110 and then connected to itself by way of a hook-and-loop configuration).

The system can harness the tension force in the strap by causing the rack 110 to oscillate vertically (e.g., when the system is the housing 100 of FIG. 1 worn on the waist and therefore in line with applied force of the strap). The spring 120 (e.g., functioning as a compression spring) can force the rack 110 back down to the neutral position in response to the strap causing the rack 110 to oscillate. This oscillation can cause the rack 110 to rotate gears in the gear set 140—illustrated as two sets of symmetrical gears—and cause the rotational magnet of the rotational magnet assembly 150 to rotate (e.g., oscillate clockwise and counter-clockwise).

FIG. 1C illustrates three different views 100C-E of the housing 100. The view 100C is a front view of the housing 100 (e.g., with a front cover removed). The view 100D is a top view of the housing 100. While views of the housing 100 are given with perspective, such as the top view 100D being where the strap can integrate, the housing 100 can function without a required orientation. The view 100E is an isometric view of the housing 100.

FIG. 1D illustrates two different views 100F-G of the housing 100. The view 100F is of a front semi-transparent view of the housing 100. The view 100G is of a top semi-transparent view of the housing 100.

FIGS. 2A-2B (collectively referred to as ‘FIG. 2’) illustrate various views of an embodiment of a housing 200. The housing 200 can function as a second energy conversion system. The view 200A is a front view of a housing 200 and the view 200B is an isometric view of the housing 200. A spring housing 210 can terminate at one end of the spring 120 of FIG. 1, while the rack 110 terminates at the other end of the spring 120. The rack 110 can move when integrated with the strap and the spring 120 of FIG. 1 can function as described above. As the rack 110 moves, the magnet housing 220 (e.g., that includes the rotational magnet assembly 150 of FIG. 1) can rotate about the coil housing 230 such that the energy is produced.

FIG. 3 illustrates one embodiment of a system 300 comprising a processor 310 (e.g., a general purpose processor or a processor specifically designed for performing a functionality disclosed herein) and a computer-readable medium 320 (e.g., non-transitory computer-readable medium). In one embodiment, the computer-readable medium 320 is communicatively coupled to the processor 310 and stores a command set executable by the processor 310 to facilitate operation of at least one component disclosed herein (e.g., a component that can perform at least part of the method 500 discussed below). In one embodiment, the computer-readable medium 320 is configured to store processor-executable instructions that when executed by the processor 310, cause the processor 310 to perform at least part of a method disclosed herein (e.g., at least part of the method 500 discussed below).

FIG. 4 illustrates one embodiment of a method 400 comprising four actions 410-440. In one example, a housing (e.g., a hardware set comprising one or more pieces of hardware) that experiences the method 400 can be integrated into a piece of hardware, such as being integrated in a running watch and used to power the running watch. The housing (e.g., housing 100 of FIG. 1 or the housing 200 of FIG. 2) can comprise a capture hardware component and/or a linear hardware component. By way of the capture hardware component and/or the linear hardware component, a linear movement can be experienced at 410. At 420, the linear movement can be converted to rotational movement. This conversion can take place by way of a conversion hardware component of the housing. At 430, the rotational movement can be used to generate an energy and can be performed by the energy generation hardware component. This energy can be, at 440, used to power the battery or a device as discussed above.

FIG. 5 illustrates one embodiment of a method 500 comprising two actions 510-520. The method 500 can be used to create (e.g., assemble) a system, such as the housing discussed above with regard to the method 400 of FIG. 4. At 510, parts can be obtained. In one example, robotic arms can physically obtain various hardware components. At 520, the system can be constructed. In one example, construction can occur by a robotic assembly mechanism. The robotic arms and/or the robotic assembly mechanism, as well as other hardware that can be used to implement the method 500, can be controlled by an industrial controller that comprises the system 300 of FIG. 3. In one embodiment, the system can be created, at least in part, by hand.

Once created, the system can be used to capture kinetic movement from a wearer and transform this kinetic movement into electrical power. As discussed above, the system can be a housing that retains hardware components and can be integrated with a rucksack, such as a rucksack used by a soldier. The soldier may carry various electronic devices and the system can be used to power those devices (e.g., wirelessly). Since the soldier can power his or her own devices, then the soldier can carry less batteries and therefore lighten his or her load. Outside of a rucksack, in addition to other examples listed above, the system can be included in an armored plate carrier (e.g., vest), civilian backpack, duffle bag, etc.

While the methods disclosed herein are shown and described as a series of blocks, it is to be appreciated by one of ordinary skill in the art that the methods are not restricted by the order of the blocks, as some blocks can take place in different orders. Similarly, a block can operate concurrently with at least one other block.
